ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

ObjectiveBased on the traditional quality evaluation methods summarized in previous dynasties, this paper systematically contrasted the quality differences between wild Polygalae Radix(WPR) and cultivated Polygalae Radix(CPR) from the aspects of character, microscope and chemical composition by modern scientific and technological means, providing a basis for high-quality production and quality control. MethodsCPR and local WPR in Yulin city, Shaanxi province from 1 to 6 years were collected, and a systematic comparative analysis was conducted using traditional pharmacognosy research methods combined with modern multi-omics analysis techniques, including character traits(length, weight, diameter), cross-sectional microscopic features(proportions of cork, phloem, xylem, etc), cell wall component content(hemicellulose, cellulose, lignin), extracts content(water-soluble extract and alcohol-soluble extract), carbohydrate content(starch, water-soluble polysaccharides), contents of total flavonoids, total saponins and specific marker compounds(3,6′-disinapoyl sucrose, polygalaxanthone Ⅲ, tenuifoliside A, tenuifoliside C, sibiricose A5 and A6) and other indexes. Ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to conduct comparative analysis of secondary metabolites in WPR and CPR, and multivariate statistical analysis such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were combined to screen the key differential components of them. ResultsIn terms of appearance, there were significant differences between WPR and CPR. The characteristics of WPR conformed to the "thick wrinkles on the epidermis" recorded in ancient books, featuring a wrinkled surface and grayish-brown appearance. However, CPR had a finer texture and a yellowish white appearance, with weight, length, and diameter increasing with longer cultivation periods. In terms of microscopy, WPR exhibited a thick cork layer with fissures in the phloem, whereas CPR had a thinner cork layer with uniformly arranged cork cells. Younger PR specimens showed numerous phloem fissures in cross-sections, while older specimens display progressively denser arrangements of phloem parenchyma cells. In terms of the contents of various major components, the contents of water-soluble extract, starch and total saponins in WPR were inversely proportional to the root diameter, while the contents of water-soluble extract, water-soluble polysaccharides and total saponins in CPR decreased with the increase of planting years. The content of xanthones in WPR was significantly higher than that of CPR, while the contents of other major components showed no significant change pattern. Among the six indicator components, the average content of sibiricose A5 in WPR was significantly higher than that of CPR, followed by slightly higher content of tenuifoliside A. In CPR, the relative content of 3,6′-disinapoyl sucrose and tenuifoliside A was the highest. The former showed an increase in volatility with increasing cultivation years, while the latter showed a decrease in volatility. The results of differential compound analysis based on UPLC-Q-TOF-MS showed that there were significant differences in metabolites between WPR and CPR samples. Among them, the seven compounds with the largest differences among WPR samples of different thicknesses were polygalasaponins, and for CPR with different planting years, the main differential compounds were oligosaccharide esters. ConclusionThere are differences between WPR and CPR in character, microscopic structure and chemical composition, and some components are inversely proportional with the increase of diameter and cultivation duration due to the distribution characteristics. However, the longer the cultivation years of PR, the closer it is to the "thick wrinkles on the epidermis" of WPR, which has been respected by generations. It is suggested that this traditional character combined with modern component contents should be used as the index of artificial cultivation and quality control of PR.

ObjectiveBased on traditional quality evaluation of Gardeniae Fructus(GF) recorded in historical materia medica, this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics, microscopic features, and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length, diameter and individual fruit weight of wild and cultivated GF, and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF, and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently, the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China, the starch content was measured by anthrone colorimetric method, the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method, the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection(HPLC-ELSD), and the contents of representative components in them were measured by ultra-performance liquid chromatography(UPLC). Finally, correlation analysis was conducted between quality traits and phenotypic traits, combined with multivariate statistical analysis methods such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA), key differential components between wild and cultivated GF were screened. ResultsIn terms of traits, the wild GF fruits were smaller, exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger, displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF, while the blue-yellow value(b*) of wild GF was significantly higher than that of cultivated GF. In the microstructure, the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals, while the endocarp contained stone cell class round, polygonal or tangential prolongation, undeveloped seeds were visible within the fruit. In contrast, the mesocarp of cultivated GF contained few calcium oxalate cluster crystals, or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like, with the innermost layer arranged in a grid pattern. Seeds were basically mature, and only a few immature seeds existed in some batches. Regarding primary metabolite content, wild GF exhibited significantly higher total polysaccharide level than cultivated GF(P<0.01). In category-specific component content, wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF(P<0.01). Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside, deacetyl asperulosidic acid methyl ester, gardenoside and chlorogenic acid compared to cultivated GF(P<0.01). Conversely, the contents of genipin 1-gentiobioside, geniposide and genipin were significantly lower in wild GF(P<0.01). ConclusionThere are significant differences between wild and cultivated GF in terms of traits, microstructure, and contents of primary and secondary metabolites. At present, the quality evaluation system of cultivated GF remains incomplete, and this study provides a reference for guiding the production of high-quality GF medicinal materials.

Da Qinjiaotang is the 54th formula of the 100 formulas in the Catalogue of Ancient Classical Formulas (the first batch) ,and it originated from the Collection of Writings on the Mechanism of Disease, Suitability of Qi, and Safeguarding of Life Discussed in Plain Questions. Da Qinjiaotang is composed of Gentiana macrophylla, Glycyrrhizae Radix et Rhizoma, Ligusticum chuanxiong, Angelica sinensis, Paeonia lactiflora, Asari Radix et Rhizoma, Notopterygium incisum, Saposhnikoviae Radix, Scutellariae Radix, Gypsum, Angelica dahurica, Atractylodis Macrocephalae Rhizoma, Rehmanniae Radix, Rehmanniae Radix Praeparata, Poria, and Angelicae Pubescentis Radix. It is a classical formula for treating strokes. Da Qinjiaotang is widely used in modern clinical practices for treating ischemic stroke, peripheral facial paralysis, cervical spondylosis, rheumatic arthritis, neurodermatitis, and other multisystem diseases. Therefore, following the Principles of Textual Research on the Key Information of Ancient Classical Famous Formulas, the authors collected the ancient Chinese medical literature of Da Qinjiaotang by the method of bibliometrics and screened out 177 valid data, involving 100 ancient books of traditional Chinese medicine. Based on the historical evolution, composition, dosage, method of preparation, and preparation of the original medicinal materials of Da Qinjiaotang, a systematic study was carried out. It was found that among the 175 records of the main diseases and syndromes, stroke (144) was the most, accounting for 82.29% of the total diseases and syndromes. Later generations mostly followed the practice of LIU Wansu in using Da Qinjiaotang to treat stroke caused by "weak blood and inability to nourish tendon", featuring "hands and feet cannot move, stiff tongue hinders speaking", as well as other symptoms, such as slant of the mouth, hemiplegia, numbness of the limbs, paroxysmal pain, and acerbic syncope. The treatment scope was expanded, covering tendon dryness, clonic convulsion, spasm syndrome, and arthralgia syndrome. At the same time, it was found that there was a controversy between "internal wind" and "external wind" in the treatment of stroke by Da Qinjiaotang. LIU Wansu thought that stroke was caused by internal factors, created the theory of "hot stroke", and used Da Qinjiaotang to treat "internal wind". Many doctors in later generations focused on treating the "external wind" of "internal deficiency and evil". There were 76 valid data on the composition of drugs, 59 of which had doses for each drug. It was suggested to use the modern conversion dosage of the original formula, with 41.30 g per dose. The drug should be boiled in 600 mL water until 300 mL, decocted once, and taken in a warm state after removing the dregs anytime. Through the analysis and study of the ancient books about Da Qinjiaotang, the paper clarified its historical evolution and confirmed its key information, so as to provide the ancient literature evidence for the research and development of the classical famous formula Daqinjiaotan and its better clinical application.

BackgroundInvasive vagus nerve stimulation therapy has been approved for the adjunctive treatment of treatment-resistant depression, which may contribute to the anti-inflammatory properties of vagus nerve stimulation (VNS), whereas the efficacy of non-invasive transcutaneous cervical vagus nerve stimulation (tcVNS) in treating major depressive disorder (MDD) and its impact on plasma inflammatory factors remain unclear. ObjectiveTo observe the effect of escitaloprom combined with tcVNS on the status of depression, anxiety and sleep quality as well as the plasma levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) in MDD patients, in order to provide references for the recovery and treatment of MDD patients. MethodsFrom August 21, 2019 to April 17, 2024, 45 patients who met the diagnostic criteria for MDD in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) were recruited from the psychosomatic outpatient clinic of the First Affiliated Hospital of Air Force Military Medical University. Subjects were divided into study group (n=23) and control group (n=22) using random number table method. All patients were treated with escitalopram. On this basis, study group added a 30-minute tcVNS therapy once a day for 4 weeks. While control group was given corresponding sham stimulation, and the duration of each stimulation lasted 30 seconds. Before and after 4 weeks of treatment, Hamilton Depression Scale-17 item (HAMD-17) was used to assess depressive symptoms, and HAMD-17 anxiety/somatization subfactor and insomnia subfactor were used to assess patients' anxiety/somatization symptoms and sleep quality. Levels of plasma IL-6 and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). ResultsThe generalized estimating equation model yielded a significant time effect for HAMD-17 total score, anxiety/somatization subfactor score and insomnia subfactor score in both groups (Wald χ2=315.226, 495.481, 82.420, P<0.01). After 4 weeks of treatment, HAMD-17 total score and anxiety/somatization subfactor score of study group were lower than those of control group, with statistically significant differences (Wald χ2=4.967, 32.543, P<0.05 or 0.01), while no statistically significant difference was found in the insomnia subfactor score between two groups (Wald χ2=0.819, P=0.366). Significant time effects were reported on plasma IL-6 and IL-10 levels in both groups (Wald χ2=21.792, 5.242, P<0.05 or 0.01). Compared with baseline data, a reduction in plasma IL-6 levels was detected in both groups (Wald χ2=22.015, 6.803, P<0.01), and an increase in plasma IL-10 levels was reported in study group (Wald χ2=5.118, P=0.024) after 4 weeks of treatment. ConclusionEscitalopram combined with tcVNS therapy is effective in improving depressive symptoms, anxiety/somatization symptoms and sleep quality in patients with MDD. Additionally, it helps reduce plasma IL-6 levels and increase IL-10 levels.

This article systematically reviews and verifies the medicinal materials of Dioscoreae Hypoglaucae Rhizoma(DHR), Dioscoreae Spongiosae Rhizoma(DSR), Smilacis Chinae Rhizoma(SCR) and Smilacis Glabrae Rhizoma(SGR) from the aspects of name, origin, producing area, quality, harvesting, processing and efficacy by consulting historical literature, in order to provide reference for the development and utilization of famous classical formulas containing the four medicinal materials. DHR, DSR, SCR and SGR have a long history of application as medicinal materials. However, due to their similar growth environment and medicinal properties, as well as their functions of promoting dampness, dispelling wind and removing numbness, there have been instances of homonymous foreign objects and homonymous synonyms throughout history, resulting in confusion of the origin. Therefore, it is necessary to conduct comparative analysis and systematic research for clarifying the historical development and changes of the four, in order to provide a basis for safe and effective medication. According to research, Bixie was first recorded in Shennong Bencaojing and has been historically known as Baizhi, Chijie, Zhumu, and other aliases. From ancient times to the mid-20th century, there has always been a situation where the rhizomes of Dioscorea plants and Smilax plants, and even the rhizomes of Heterosmilax plants, were mixed together to be used as medicinal herbs for Bixie. However, since the Tang dynasty, it has been clearly advocated that the rhizomes of Dioscorea plants have excellent quality and have been the mainstream throughout history. The 2020 edition of Chinese Pharmacopoeia categorized it into two types of medicinal herbs(DHR and DSR). Among them, the origin of DHR is the dry rhizomes of Dioscorea hypoglauca, and the origins of DSR are the dry rhizomes of D. spongiosa and D. futschauensis. In ancient times, due to different types, the corresponding production areas of DHR and DSR were also different. Nowadays, They are mainly produced in the southern region of the Yangtze River. Since the Tang dynasty, the quality of Bixie has been characterized by its white color and soft nature. In modern times, it has been summarized that those with white color, large and thin pieces, powdery texture, tough and elastic texture, and neat and unbreakable are the best. The harvesting times of DHR and DSR are in spring or autumn, with the best quality harvested in autumn. The mainstream processing methods of them are slicing and then using the raw products or wine-processed products. SCR was first recorded in Mingyi Bielu and has been known as Jinganggen, Tielingjiao, Tieshuazi, and other aliases in history. The mainstream source is the dry rhizomes of Smilax china in the past dynasties, with the best quality being those that are tough and rich in powder. The harvesting time is from the late autumn to the following spring, and the main processing method throughout history has been slicing for raw use. SGR was first recorded under the item of Yuyuliang in Variorum of Shennong's Classic of Materia Medica. It was listed as an independent medicinal material from Bencao Gangmu. In history, there were such aliases as Cao Yuyuliang, Lengfantuan, Xianyiliang, Tubixie, etc. The main source of the past dynasties was dry rhizomes of S. glabra. In history, there have also been instances of multiple plants belonging to the same genus, and even cases of mixing the rhizomes of plants in the genus Heterosmilax. It is mainly produced in Guangdong, Hunan, Hubei, Zhejiang, Sichuan, Anhui and other regions, its quality has been summarized as large in size, powdery in texture, with few veins, and light brown in cross-section since modern times. The harvesting time is in spring or autumn, and the main processing method throughout history has been slicing for raw use. DHR, DSR, SCR and SGR all have the effects of promoting dampness, dispelling wind, relieving rheumatism and detoxifying. However, their detoxification abilities are ranked as follows:SGR>SCR>Bixie(DHR and DSR). Especially for the treatment of limb spasms, arthralgia and myalgia, scrofula, and scabies caused by syphilis and mercury poisoning, SGR has a unique effect. Based on the research results, DHR is recommended to develop the famous classical formulas containing Bixie as the first choice for medicinal herbs. It should be harvested in autumn, sliced thinly while fresh, and processed according to the requirements of the famous classical formulas, without any requirements for raw use. Selecting the rhizomes of S. china, harvested in late autumn, and thinly sliced while fresh. If there are no special processing requirements in the formulas, use it raw. Selecting the rhizomes of S. glabra, it is harvested in autumn and thinly sliced while fresh. If there are no special processing requirements in the formulas, raw products can be used.

[Objective] To study the molecular biological mechanism for a case of ABO blood group B subtype, and perform three-dimensional modeling of the mutant enzyme. [Methods] The ABO phenotype was identified by the tube method and microcolumn gel method; the ABO gene of the proband was detected by sequence-specific primer polymerase chain reaction (PCR-SSP), and the exon 6 and 7 of the ABO gene were sequenced and analyzed. Homologous modeling of Bw.03 glycosyltransferase (GT) was carried out by Modeller and analyzed by PyMOL2.5.0 software. [Results] The weakening B antigen was detected in the proband sample by forward typing, and anti-B antibody was detected by reverse typing. PCR-SSP detection showed B, O gene, and the sequencing results showed c.721 C>T mutation in exon 7 of the B gene, resulting in p. Arg 241 Trp. Compared with the wild type, the structure of Bw.03GT was partially changed, and the intermolecular force analysis showed that the original three hydrogen bonds at 241 position disappeared. [Conclusion] Blood group molecular biology examination is helpful for the accurate identification of ambiguous blood group. Homologous modeling more intuitively shows the key site for the weakening of Bw.03 GT activity. The intermolecular force analysis can explain the root cause of enzyme activity weakening.

BACKGROUND:Our previous study found that Modified Erxian Pill could alleviate inflammation in collagen-induced arthritis rats,but its mechanism needs to be further verified. OBJECTIVE:To analyze the components absorbed in the blood of Modified Erxian Pill,and observe the effect of the drug-containing serum of Modified Erxian Pill on pyroptosis of J774A.1 macrophages. METHODS:(1)Analysis of components absorbed in the blood of Modified Erxian Pill:Ultra-high performance liquid chromatography-high resolution mass spectrometry was used to detect and identify Modified Erxian Pill and its components absorbed in the blood.(2)Effect of the drug-containing serum of Modified Erxian Pill on pyroptosis of J774A.1 macrophages:Molecular docking technology was used to initially verify the sesquiterpenoids and NLRP3 in components absorbed in the blood of Modified Erxian Pill.J774A.1 macrophages were randomly divided into blank control group,lipopolysaccharide+adenosine triphosphate group,and lipopolysaccharide+adenosine triphosphate+Modified Erxian Pill with low(2.5%),medium(5%),and high(10%)dose groups.The release of lactate dehydrogenase in the cell supernatant of each group was detected according to the kit instructions.The levels of interleukin-1β and interleukin-18 in cell supernatant were detected in each group by ELISA.The cell membrane damage was detected by Hoechst/PI staining.The expression levels of NLRP3,Caspase-1,GSDMD,and GSDMD-N protein in the cells of each group were detected by western blot assay. RESULTS AND CONCLUSION:(1)A total of 32 active components of Modified Erxian Pill were identified,and 21 components entered the blood.The main components into blood included a variety of sesquiterpenoids.(2)Molecular docking results showed that 3-O-Acetyl-13-deoxyphomenone,Incensol oxide,Atractylenolide III,Rupestonic acid,and 3,7-Dihydroxy-9,11-eremophiladien-8-one had good binding activity with NLRP3.(3)Compared with the blank control group,lactate dehydrogenase activity and the expression levels of interleukin-1β and interleukin-18 were significantly increased in cell supernatant of lipopolysaccharide+adenosine triphosphate group(P<0.001).Hoechst/PI staining showed that the number of PI-positive cells was significantly increased.After the intervention of lipopolysaccharide+adenosine triphosphate+Modified Erxian Pill group,all of them showed different degrees of reduction.(4)Compared with the blank control group,NLRP3,Caspase-1,GSDMD,and GSDMD-N protein expression levels were significantly increased in the lipopolysaccharide+adenosine triphosphate group(P<0.05).Compared with lipopolysaccharide+adenosine triphosphate group,the protein expressions of NLRP3,Caspase-1,GSDMD,and GSDMD-N were significantly decreased in the lipopolysaccharide+adenosine triphosphate+Modified Erxian Pill group(P<0.05),and had a certain dose dependence.These findings verify that the drug-containing serum of Modified Erxian Pill may inhibit the pyroptosis of J774A.1 macrophages by regulating the NLRP3/Caspase-1/GSDMD pathway.
